I have now 3 days AVAST4Home,and i am looking for the best Free
Firewall for this program,version 4.7
Who can help me?
my reccomendation would be Kerio (google will find it) and set it up for simple or advanced depending on how seriously you want to monitor its performance.
good luck 
I just love the great free firewall Comodo Personal Firewall
http://www.personalfirewall.comodo.com/
Work just fine for me with Avast
The best :o
Comodo Personal Firewall 
See some firewall tests for comparison, some are freeware but many are paid for versions http://www.firewallleaktester.com/tests.php. Also see http://www.thefreecountry.com/security/firewalls.shtml
Comodo is great!
I’m using Sunbelt Kerio Personal Firewall. I love its simple interface which easy to understand, I like its application behavior blocking that gives me some kind of proactive protections.
Hi Cactus :
There is NO "best free firewall"; just need to find one that
suits you . For starters, would recommend you view the
info at www.spychecker.com/software/freeware_firewall.html .
I, personally, like the FREE Sygate, that is listed at
www.filehippo.com/software/firewalls/ because there is
a "Setup Guide" available .
COMODO or Jetico 1.0.1.61 are very avast! friendly
Another plug for Comodo. Apart from an old Norton one (2000 I think, it was great!) and XP’s inbuilt, it’s the only other I’ve used. Seems effective, easy to use, passes the ShieldsUp test (all service ports) and doesn’t use much cpu/ram.
I read the leaktest a few weeks a go.
And see the Firewall of Windows. very bad.
Now must i tell you that i earlier this year used the Kerio Firewall,
and this is a very good one,only now i have him in the freeversion
on me computer. So i ask by my self ,is the Free Kerio O,K?
Then have i running Webroot Spysweeper (very good) and now Avast4Home.
A few guys prefeer Comodo, and i think that i Comodo install and then
can i say whats better is.
I know its a personal tasty,but there is no Firewall (even Buy) with
a score off 100% .
Let me thank all off you for reacting on me question,and the fact
that i already have a good one.
Yes, it is a very good firewall.
The one you like, works, does its job.
Both Comodo and Kerio are good firewalls.
My friend - a big guru in IPS - says he won’t recommend COMODO anymore. The reason is as follows (from his words): COMODO doesn’t process connections at high-number ports from 65000 to 65535.
So then… what to use? ???
If you look for a free firewall, Kerio will be a good choice. It may defend you from unknown viruses. It has deep drivers, it is practically fully functional, etc.
Hi ,I did a port scan at grc.com on ports 65001-65064 and got stealth results.See screenshot of cpf logs.
I use Sygate for 5 years with Avast and other anti-virus with Windows XP/SP2
Sygate is a freeware; it’s very easy to use and to control

Yes agree Sygate is a good Firewall,but
i have problems whit the use of CPU,this is very high,i think.
O.K.Its true the firtst month after install you get the full PRO
programm,but i pay never whit creditcards,so if i not pay is the Kerio Firewall
automaticly Freeware.
And thats means,no virus or Troyan horse and other stuff are cathing annymore.
Olso a few other things are in the Freeversion not working.
But it is and stay a good and very to understand Firewall.
The fact that Kerio now not running on virus,etc,is for me not bad,becouse
i use Webroot Spysweeper and this programm replace The Kerio Pro,
in combination whit SpywareBlaster and AVAST4Home.(whit the Free Kerio)
Anyone considering Sygate should consider a couple of things, it is no longer in development since it was bought out. It has a localhost loopback weakness, in that it can’t tell what programs are using the localhost proxy it only identifies the local host proxy. So it is possible that a malicious program could use the localhost proxy and not be challenged if the proxy is allowed permission to connect to the internet.
avast’s Web Shield proxy is one such proxy, however avast’s web shield doesn’t allow all and sundry to use the web shield proxy only browsers that are known not to cause problems, so this might limit exposure to the Sygate weakness.
To further improve this security, you should disable transparent use of the web shield proxy. How to disable transparent web shield proxy and allow only those browsers you want use it:
In avast! go to Web Shield provider, Customize…, Basic tab, blank the redirected HTTP port field (remove the 80). Now no browser can use web shield unless you manually configure it to use Web Shield.
